The move comes after Water Works officials said they pumped a record 95.64 million gallons of water on Monday. The previous record of 92 million gallons was set in June 2006.

Officials said that in addition to the record water use, the water quality of source waters is creating treatment issues.

Stage 1 of the plan requires water usage to be reduced by 10 percent.

Water Works CEO Randy Beavers said it's the first time since the late 1970s Des Moines has imposed a stage 1 conservation plan. It's voluntary but strongly encourages homeowners to shut off sprinklers or cut volume of water used.

1. Water lawns early in the morning, prior to 6:00 a.m., to take advantage of the coolest times when the evaporation rate is less. Irrigating in the evening may result in potential fungus development on the lawn.

2. Check the interior plumbing for faucet or toilet leaks, and make the necessary repairs. To detect potential leaks, listen for trickles of water or frequent water valve operations.

3. Clean outside surfaces such as patios, driveways, and sidewalks using a broom rather than a hose.

4. Wash vehicles with a bucket and hose that has a shut-off nozzle, rather than continuously running a hose.

5. Fill sinks with water for tasks such as washing dishes, preparing food, brushing teeth, and shaving rather than leaving water running.

6. Suggest installing water-saving devices in showers.

7. Use automatic dishwashers and washing machines with only full loads whenever possible.

8. Store a container of drinking water in the refrigerator rather than running water from the faucet to cool it.

9. Encourage wise use of water during outdoor play, e.g., playing in the sprinkler, water toys, and swimming pools.
